What can gravitational waves teach us about the universe?

AI Thread Summary
Gravitational waves are ripples in spacetime caused by the movement of massive objects like stars and black holes, a concept introduced by Einstein's theory of relativity. While they have not yet been physically detected, they represent a significant area of study in astrophysics. Newcomers to the topic may find it challenging to grasp the concepts initially, but understanding will develop over time with continued learning. Participants encourage asking questions and engaging further to deepen knowledge. The discussion highlights the importance of curiosity and persistence in exploring complex scientific ideas.

Welcome to PF :)
Gravitational waves are ripples in the space time. Moving masses like stars and black holes do create the gravitational wavers. They are not yet detected physically but it is just a concept stated by Einstein in his theory of relativity. Well, you can go google it for more info and if you have any more doubts, free feel to drop them here :)
 
thank you.:smile: (even though i didn't understand it , looking forward to learn about these.)

Its k.. Yo will get it in the process...I don't think you can understand the terms at the initial stage itself ! Keep posting :)
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect...

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
